How do you reset the "Check Air Bag" dash light? Vehicle is a 97 GMC Jimmy,
4wd, 192K. All connections from the front impact sensors to the steering
wheel have been checked and there does not appear to be any issues with
them. No other lights are on. I want to reset it to see if it was just a one
time thing or something else. Vehicle has never been in collision or
anything that would have impacted this system.
The ONLY way to reset an air bag warning is to take it to a shop with
the proper equipment and have them check the code that set the light.
They need a dealer level scan tool with all the functions. Then either
you can repair the problem or pay them to do it.
The air bag light is NOT like the CEL or the ABS light. When it is on
the air bags will NOT work PERIOD. It may be a broken clock spring, bad
sensor, bad air bag module or something else.
Thanks Steve for info,
Took it in. According to them (Chevy Dealer) it is a bad SDM unit (they told
me diag computer when asked but is this not the black box data recorder?).
Cost is $475 installed. Will have it back tonight.
Now the question is, Have I been hosed in the costs? Sounds to be to much
based upon what I can pull up in gmparts direct, but I guess you have to
have the durn computer to read it.
It is the sensing and data module. It watches the airbag sensors, seat
belts, brake light switch and speed sensor and a couple other items.
It is not a real common failure item though. It could be that the
connector is going bad on the module. Price wise that isn't out of line.
It is not real easy to work on and you need to be able to reprogram the
BCM to recognize the new unit.
